INDICATIONS FOR PROCEDURE: A 62-year-old female with a history of mitral valve disease.

PROCEDURE IN DETAIL: The patient was brought to the nuclear suite at which time rest dose of thallium was injected via peripheral vein followed by the rest scan images. For the stress portion a stress dose of Lexiscan was injected via peripheral vein followed by the stress scan and Myoview, followed by the stress scan images. There were no complications.

FINDINGS:
Hemodynamics. Resting blood pressure 120/90 with a heart rate of 69. During Lexiscan infusion blood pressure was 116/80 with a heart rate of 106. Resting EKG revealed sinus rhythm, otherwise normal EKG. During Lexiscan infusion there were no acute ST-T wave changes. No chest pain with exercise. No arrhythmia with exercise. Reason for termination was completion of protocol.
Gated wall motion analysis revealed a left ventricular ejection fraction of 58% without evidence of segmental wall motion abnormalities.
Perfusion images. SSS score of 9, SRS of 3, SDS of 6. Lung-heart ratio of 0.36. TID score of 1.31. Resting perfusion images showed a moderate area of inferior wall fixed defect. During stress there was partial reversibility of the same region.
